Solar and wind power are important, but really solving the climate crisis will take a whole new generation of energy-efficient technologies, and even new companies to develop them. But there's a growing force in the field — the green tech incubator.

Congress just passed legislation to create a national GMO labeling standard. If signed into law, it would override more stringent measures that went into effect in Vermont on July 1. Neither the food industry nor advocacy groups that oppose GMOs are pleased with the result.
